Gender identity refers to a person's internal sense of their own gender. This is different from sex assigned at birth, which is typically based on physical characteristics observed when a baby is born. Many people's gender identity matches the sex they were assigned at birth, while others experience a gender identity that differs from that assignment.

A person might be assigned male at birth but have a gender identity as a female, or vice versa. Some people identify outside the binary of male and female entirely, using terms like non-binary, genderqueer, or other identities that reflect their personal understanding of their gender. Gender identity is a fundamental part of who someone is, and it typically develops early in childhood, though people may not have words to describe their identity until later in life.
The term "transgender" describes people whose gender identity differs from the sex they were assigned at birth. "Cisgender" describes people whose gender identity matches their sex assigned at birth. Both are neutral descriptive terms. Understanding these definitions helps create respectful communication and better understanding between people with different gender identities.
Research from the American Psychological Association indicates that gender identity is established relatively early in development and is not changeable through external pressure or intervention. Gender identity differs from sexual orientation, which describes who someone is attracted to. A person of any gender identity can have any sexual orientation.
Practical takeaway: Gender identity is an internal sense of one's gender that may or may not match the sex assigned at birth. Learning these basic definitions and terms helps in understanding yourself and others better.
Three distinct but related concepts are often confused: biological sex, gender identity, and gender expression. Biological sex refers to physical and chromosomal characteristics, typically categorized as male or female at birth, though some people are born with variations in these characteristics. This is the medical or clinical designation made by healthcare providers.

Gender identity, as mentioned previously, is a person's internal sense of their gender—how they understand themselves in terms of gender. This is psychological and personal. Gender expression, by contrast, refers to how a person outwardly demonstrates or communicates their gender through clothing, hairstyle, behavior, voice, mannerisms, or other characteristics. Gender expression can vary widely among people with the same gender identity and may change throughout a person's lifetime.
Consider these examples: A person assigned male at birth might have a gender identity as female and express that identity through clothing typically associated with women, while another person assigned male at birth might have a non-binary gender identity and express it through a combination of masculine and feminine clothing and presentation. Two women might have identical gender identities but very different expressions—one might wear makeup and dresses while another might wear no makeup and favor jeans and t-shirts. Both expressions are equally valid.
Understanding these distinctions matters because it allows for more accurate conversations about gender. When discussing someone's gender, it is important to recognize that you cannot determine someone's gender identity by looking at them or observing their gender expression. Assumptions based on appearance can be inaccurate and disrespectful.
Practical takeaway: Biological sex, gender identity, and gender expression are three separate concepts. Someone's appearance or presentation does not indicate their gender identity.
The language around gender identity continues to evolve as more people have opportunities to discuss and share their experiences. Learning current terminology can help in understanding discussions about gender and in communicating respectfully with people of various gender identities.

Some commonly used terms include: Transgender (a person whose gender identity differs from sex assigned at birth); Cisgender (a person whose gender identity matches sex assigned at birth); Non-binary (a gender identity that falls outside the categories of exclusively male or female); Genderqueer (similar to non-binary, describing a gender identity that is fluid or exists outside traditional categories); Agender (identifying as having no gender or a neutral gender); Gender non-conforming (a person whose gender expression does not conform to cultural norms associated with their assigned sex); Two-Spirit (a term used by some Indigenous North American people to describe gender identities outside the Western binary); and Demigender (identifying partially with a particular gender).
Pronouns are also an important aspect of gender identity and expression. Many people use he/him, she/her, or they/them pronouns. Some people use other pronouns like ze/zir or neopronouns. A person's pronouns may or may not align with assumptions based on their appearance. When uncertain about someone's pronouns, it is respectful to listen for how others refer to them or, in appropriate contexts, to ask politely.
Language also includes terms related to gender transition. Transition can refer to social changes (like changing name or pronouns), medical changes (like hormone therapy or surgery), or both. Not all transgender people transition medically, and transition looks different for different people.
Practical takeaway: Gender-related terminology includes specific terms for various gender identities and experiences. Using accurate language shows respect and helps facilitate clearer communication.
For some people, understanding their gender identity is straightforward. For others, it is a process of exploration and reflection. If you are questioning or exploring your own gender identity, this guide offers information about common experiences and thoughts that people report during this process.

Many people describe feeling a disconnect between their assigned sex at birth and their internal sense of gender. This disconnect might be subtle or pronounced. Some people report noticing this feeling from childhood, while others recognize it only as teenagers or adults. There is no single "correct" age or timeline for recognizing or understanding one's gender identity.
Common reflections people describe include: noticing preferences for activities, clothing, or toys typically associated with a different gender; feeling uncomfortable with physical changes during puberty; experiencing distress about being referred to by certain pronouns or names; feeling more comfortable when others perceived them as a different gender; having a persistent sense that their assigned gender did not fit; or gradually realizing that terms like "transgender" or "non-binary" resonated with their experience.
Exploration might involve private reflection, journaling, reading stories of other people's experiences, or talking with trusted friends or counselors. There is no requirement to rush to a conclusion or label. For some people, exploration leads to a clear sense of their gender identity. For others, understanding remains fluid or evolves over time, and this is equally valid.
Mental health professionals, particularly those with training in gender identity issues, can provide a supportive space for exploration. These conversations are confidential and designed to help you understand yourself better, not to push you toward any particular conclusion or outcome.
Practical takeaway: Exploring your gender identity is a personal process with no set timeline. Reflection, information, and conversations with trusted people can support your understanding.
Numerous organizations, publications, and online resources offer information about gender identity. These range from peer-support communities to research-based educational materials.

The American Psychological Association and American Medical Association both have published information about gender identity. University libraries and research databases contain peer-reviewed articles about gender identity, gender development, and related topics. These academic sources can provide detailed information grounded in research.
Support groups exist in many communities, both in-person and online. These groups allow people to connect with others who share similar experiences and to learn from one another. Online forums and communities focused on gender identity exist on various platforms, though quality and accuracy vary, so it is wise to cross-reference information from multiple sources.
If you decide to speak with a mental health professional, seeking out someone with specific training and experience in gender identity is important. Professional organizations like the Association for Transgender Health and the World Professional Association for Transgender Health maintain directories of providers. Many therapists specialize in supporting people exploring their gender identity.
Educational institutions increasingly offer resources related to gender identity. Some schools and universities have resource centers, support groups, and trained staff to discuss gender identity issues. Workplaces may also have employee resource groups or human resources staff who can provide information and support.
